DAWN, n. The time when men of reason go to bed. Certain old men
prefer to rise at about that time, taking a cold bath and a long walk
with an empty stomach, and otherwise mortifying the flesh. They then
point with pride to these practices as the cause of their sturdy
health and ripe years; the truth being that they are hearty and old,
not because of their habits, but in spite of them. The reason we find
only robust persons doing this thing is that it has killed all the
others who have tried it.
-- Ambrose Bierce, "The Devil's Dictionary"
